PRINTING ATTACHMENT FOR ROTARY PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 417,509, dated December 17, 1889. Application filed November 3, 188i}. $eria1No. 290,062. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES N. ROBERTS, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and printing-machines upon which newspapers are printed from a roll of white paper, and usually known as high-speed-cylinder newspaper printing presses, my improvement forming an adjunct thereto whereby the margin of the paper may be utilized and printed upon, as well as the. body thereof.

In the operation of printing newspapers upon-presses of this kind it is necessary that a blank margin of about one inch be allowed to remain upon either side of thesheet of paper as it enters the press from the roll, in order that the tapes and grippers may engage the same in the operation of carrying the sheet through the press. This said blank margin, on account of its specially-prominent position, would be, if utilized for advertising purposes, of great value.

My said improvement consists of such mechanism as may print any desired matter, in any desired color, upon the margin usually 'left blank, (for the reasons aforesaid,) as the paper is unrolled before entering the press, thus leaving the margin thus printed-free to be engaged, operated upon, or held by the tapes or other engaging part of the press while the paper is passed through the press and the body thereof printed upon in the usual manner. The mechanism which I use to attain this end consists of a narrow-faced cylinder, (the thickness thereof conforming to the width of margin to be printed,) upon which may be engraved the characters which it is desired to print upon said margins, or upon which may be affixed movable types or plates of rubber, metal, orother substance capable of transmitting a legible impression upon paper. This cylinder is equipped with inking apparatus, governing and operating appliances, as hereinafter described, and affixed to the press at such desirable point that it may operate upon and print characters desired upon the margin of the paper before the same is engaged by any of the mechan ism of said press operating as aforesaid upon said margin.

The construction and operation, as well as the individual and combined utility of the several parts of ,my said invention, may be better shown and described by reference to the accompanying sheet of drawings, which is hereby made a part of this specification.

Upon the said sheet of drawings, Figure 1 shows a side elevation of a portion of the foot-plate or shoe of a cylinder printing-press, the journal-bracket and paper-cylinder thereon, and attached thereto my improvement, the subject of this specification. Fig. 2 shows a longitudinal elevation of paper roller with my improvement thereon, shown in vertical section. Fig. 3 is a vertical section showing the constructional features of the inking device I use upon my invention. Fig. 4 is atop plan of one of the constructional elements of my invention, which is designated by letter O, and is hereinafter fully described.

In the several figures like letters of referively, upon the supports C C.

E is the shaft of the paper-roll core, and is journaledat its respective ends in the journal-boxes DD.

F is a narrow-faced cylinder, upon the face of which may be engraved or affiXed types, cuts, or dies capable of printing an impression when impressed upon paper, and is placed in such relative position to the paper roll thatits face bears upon the margin of the paper.

H H are two uprights placed, respectively, on either side of printing-cylinder F, and each bored to receive the j onrnal-sha ft of said cylinder. The lower ends of these uprights are severally weighted, as indicated by M, with snilieient heft to swing them by gravity upon the loose journal-shaft of cylinder F, and then cause them by gravity to assume and retain a vertical position, the upper parts of said uprights extending upward a short distance above the topmost point of the circumference of said cylinder F. J ournaled into these said uprights, above the cylinder F, are two ink-rollers I and L, being respectively a distributive roller and an inking roller for the surface of cylinder F, and supported at the upper extremity of said uprights is an ink-supply fountain P.

I and L are respectively the distributing and inking rollers above referred to, placed between and jonrnaled into the uprights II and II, the face of the lower or inking roller L resting upon the face of printing-cylinder F, and the upper or distributing roller I engaging the upper surface of inking-roller L.

M indicates the lower or weighted end of upright II.

N is an upright arm extending from any convenient part of the press-frame to a point about even with the top of the paper roll when full.

0 is an extension aifixed by a pivoted joint to the upper end of arm N, the end of extension 0 being in the shape of a fork, as shown specifically in Fig. 4.. The ends of the fork are bored to form bearings for the journalshaft of cylinder F, which said cylinder and the uprights II and II are placed to operate in said fork.

P is the ink-fountain above referred to, and is fixed at the upper end of the said uprights II and H.

R indicates a valve in fountain I, whereby the flow of ink from said fountain to distribn tin g-roller I may be regulated and governed.

T indicates the point at which the extension 0 is aifixed to the arm N, as aforesaid.

In the operation of my invention as above constructed the extension 0 of arm N, in the,

fork of which is journaled the printing-cylinder F, is bent over at the joint, so that the circumferential face of cylinder F comes in contact with the outer margin of the paperforming roll A.

I11 the operation of the printing-press the paper on roll A is drawn inward to be printed from the roll in the direction and manner i11- dicated by A and the arrow placed near the extended sheet shown in Fig. l. Ink flows from fountain P through valve R to distributingroller below, from thence to inking-roller, and

is then and therefrom imparted to the characters engraved upon or afiixed to the face of the printing-cylimler F. As the paper is drawn into the press, as aforesaid, the roll A is revolved in the direction indicated by the arrow placed thereon. As the face of printing-cylinder F bears, as aforesaid, frictionally upon the margin of the paper in said roll and is there held by its own weight, assisted by the suspended weight M, and, consequent upon the revolution of said cylinderroll A, cylinder F is correspondingly revolved by frictional contact and an impression of the characters engraved or affixed to the surface thereof is imprinted therefrom upon the margin of the said paper upon the said roll. It is intended that the circumference of the printing-cylinder F shall equal the length of the sheet of each newspaper, whereby the impressions printed at each revolution'of said cylinder may be caused to appear upon the margin of each newspaper printed, and as the printing-cylinder F is suspended upon the extended arm 0, playing upon pivot-joint T, the said cylinder by force of gravity hugs the roll of paper, and as the roll of paper decreases in size byits expenditure the said extension of arm 0 so governs the said printing-cylinder that it constantly holds the same relative position to the roll as it decreases and continually snstains'its frictional relation thereto, whereby it imparts the imprint of its surface to the margin of the decreasing roll.

Having in the hcreiubefore manner and form described the component parts, their respective utility, the combinations thereof, and also the utility and general construction of my said improvement, I therefore claim as my invention Upon a printingpress printing from a roll,

of paper, a narrow printing-cylinder so placed as to engage the outer margin of the paper upon said roll, and in combination therewith an inking apparatus consisting of inking roller or rollers and ink-fountain afiixed to two upright parts, said upright parts being suspended from the journal-shaft of said cylinder and having their lower end weighted with sutlicient weight to cause the said upright parts to assume and continually retain a vertical position, all as above described, set forth, and specified.

In witness whereof I have hereunto ailixed my signature at Chicago, aforesaid, in the presence of two subscribing witnesses, this 20th day of October, 1888.

CHARLES N. ROBERTS.

In presence of W. KNOX HAYNES, CHARLES T. BLAcKwELL.
